KEDAR HARTLEY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, OF ONE-HALF TO JOSEPH HANSON, OF SAME PLACE.

LOOM FOR WEAVING CHENILLE AND FRINGE.

SPECIFICATION forming part of Letters Patent No. 396,205, dated January 15, 1889.

Application filed April 22, 1387- Serial No. 235,726. (No model.)

To (LZZ whom it may concern.-

rle it known that I, KEDAR HARTLEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Looms for eaving Chenille and Fringe; and I do declare the following to be a full, clear, and exact description of the invention, such as will en- I o able others skilled in the art to which it appertains to make and use the same, reference be ing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention. relates to looms, and has more especial reference to that class of looms used in the manufacture of fabrics which are intended to be cut into longitudinal strips to form chenille filling or woof for use in making rugs.

The main points of construction which constitute the novel features of the present invention may be enumerated as follows: first,

the device for holding the weft or filling threads; second, the means for causing any one of a series of such devices to be elevated into position beside. the warp-threads; third,

means for adjusting such device laterally when it is adjusted vertically; fourth,a cutting device for severing said weft-thread at or near the holding device after the nippers have drawn it through the shed; fifth, means for giving the pattern-card and its supporting and feeding means the necessary lateral adjustment to receive a needle from any one of two or more vertical lines of needles, and various details of construction and combinations of parts constitute other points of improve- 0 ment, as will be hereinafter described, and

pointed out in the claims.

The accompanying drawings illustrate what I consider the best means for carrying my invention into practice.

Figure 1 is a side elevation of the loom complete with all my appliances and improvements attached. Fig. 2 is a front elevation of the same. Fig. 2 is a detail view of the mechanism for opcratin the drum from which the thrust-arm is actuated. Fig. is a detail-i view, partly in section, showing particularly the devices for holding and cutting the filling-threads. Fig. 4 is a partial plan of the devices shown in Fig. 2. Fig. 5 is a side elevation of the devices shown in Fig. 3, taken from 5 5 the left hand thereof, and in addition means for holding a selected weft-holder elevated. Fig. 5 is an enlarged view of athread-holder. Fig. 6 is a side elevation, on an enlarged scale,

of the Jacquard mechanism and card. Fig. 7 is a section of Fig. 6 on the line X Y, looking down. Fig. 8 is a detail view of a part of the Jacquard mechanism, taken from Fig. 1, looking in the direction of arrow No. 1. Fig. 9 is a detail of a portion of the card-carrying device. Fig. 10 is a vertical section on the line V \V of Fig. 6.

Similar letters and figures of reference indicate corresponding parts in all the figures where they occur.

A is the fixed frame of the loom, and A the harness mechanism,which operates the warpthreads, and which is of the ordinary style well known in looms and need not be particularly described here.

A represents the finished fabric, which is afterward cut into strips for furnishing the filling for rug-weaving. The character of this filling is well understood, it consisting of two or more warp-threads and a series of short weft-pieces, which form the nap of rugs, the warp-threads of the loom herein shown being disposed in sets or pairs,with a short distance between each two adjacent sets or pairs,which space affords a line to be cut by suitable machinery to furnish the nap of rugs, as aforesaid, when such strips are woven into rugs; but, as the particular use of the goods produccd is not essential to the construction and operation of the machine herein described, it will be understood in the outset that I do not make this explanation in order to limit the uses of my machine, but simply to give a clearer understanding of its parts and purposes.

O C are the take-up .rolls for the goods after being woven. These take-up rolls are of the well-known form and are placed and operated in the usual way.

I will first describe the tlnread-holding devices and the means for operating them. These devices, of which there may be any desired number, consist of a standard or stem, (I, on the upper end of which is a head having an inward projection, (7', having a channel or groove open on top and registering with an opening, (7 through the head of the stem, and a hinged arm, (1, which drops by gravity down into the said groove or channel and forms a tension for the wel't-thre:ul d, which is passed through the opening (I and lies in the said channel under the arm. The front end of the arm (1 is finished with a dowil'wardlyn'ojectin beak or extension, (1, which drops over the end of the projection d and further increases the tension upon the weft-threads, the under side of the beak being grooved to hold the weft yarn or thread (1* centrally under it. The rear end of hinged arm is pivoted or hinged in a portion of the head of the stem, which projects or extends above the projection (Z. A set? or series of these thread-carriers, which, as a whole, I shall denoniinate or mark 1) for sake of perspicuity in the further description, are held in a sliding frame or carriage, E, which is mounted upon a bar or way, e, held in the fixed frame of the machine. An y number of holders maybe employed, according to the number of colors designed to be used.

The holders 1.) are held in the carriage E with liberty to move up and down therein, while the carriage is capable of lateral movement on the bar 0.

The vertical movement of the holders is a separate and independent action brought about in each holder separately and independently by means of connections from the Jacquard harness, which hits the holder to the proper vertical position, and when thus elevated the lateral adjustment of the carriage and holder takes place by means ol mechanism which will presently be described.

For the purpose of having 1 he Jacquard harness raise the holder, a lever, f, is provided For eachholder, to which a connection, from the Jacquard harness is attached. The leversfarc let into openings (1 in. the stems of the holders D at one end and pivoted to a portion of the carriage E at the other, while the connection f is attached at some suitable point to the lever. The means for causing this elevation of the lever by the Jacquard harness will. be presently explainml. As soon as the holder is raised by the Jacquard. connection, a lateral adjustment of the frame or carriage E takes place to bring the holderin line with the shed of the warp-threads. This adjusting means consists of a pair of pushers, 5 g], mounted on a slide-bar, g, and connectml by cords 1* 51 to a drum, G, and wound in reverse directions on said drum. This drum is given a partial rotation in one direction at the elevation of each holder D by means of the crank-arm G, pitman G and pivoted lever G, which is opera-ted on by a cam, G, on a shaft, ll, suitably driven by power. \Vhen the drum receives this partial rotation, the pushers g g are caused to center upon the slide-bar g, and will push the carrier or holder 1), with the carriage in which it is held, into the space between the said pushers when thus drawn together, and hold it there until the drum is turned in the opposite direction and the pushers are released. This OpDOSli/O movement of the drum is acctnnplished automatimrlly by a spring, which is distended as the drum is being ro' tated to center the holder, as above described,

- and which will by its recoil throw the drum back into its normal position as soon as the action ol cam (wt upon lever G completed. As soon as the holder 1) is (("iliUl'Otl, as above describial, the Jacquard connection maybe released, and it is desirable that it should be released, so that the action of the Jacquard harness may not be impeded nor delayed by haying to sustain the holder from the said harnc s. For the purpose of supporting the holder when thus elevated and centered, so that the strain upon the Jacquard harness may be released, I 1n'ovide a vertieally-inov ing supporting-stick, l), which is caused to rise and rest under the lower end of the stem of the holder as soon as the same is centered. The lower end of the stem is hollowed out to receive the rounded or pointed upper end of the stick I). This stick 1) is carried by a lever, D", which is pivoted at its rear end, and is operated upon by a cam, D", on the same shaft, ll, with cam G". The time 01' action of these cams so regulated that the le ver G shall. first be elevatca'l, and then the lever D 'hen the holder 1) is thus elevated and centered, the thrust-arm I, with nippers I, is thrust forward or inward from the opposite side of the warp-threads, and by means oi. the arrangcment olf jaws and springactuated stop or projection l (shown in Fig. -l) the nippers are tirstopened to receive the weft-yarn between them, and then closed upon it, and then drawn across between the warp-yarns. ()ne jaw ol? nippers l is provided with a-projcction, '1', which comes into the path olf the stop I inv the torward movement and opens the nippers. On the backward movementthis stop is pushed outol' the way by the projection i. The means for thus advancing and retrz'icting the arm I consists of cords c" and c, which are attached to the said arm and wound in opposite directions on the drum mounted on a shaft, c, which is rotatml first; in one direction and then in the other by means of the gear (1" and segment: c which is operated by a link, 0, t'rom a crank, c, on a shaft, c, as shown in Fig. 2, said shal't e lying directly back of shaft c in Fig, 2, and hence not showing therein. As soon as the weft-thread is drawn across the warp-threads it is cut oil? at the holder end by means of a knife, J, which is held to move vertieallyin guides j j, and is connectei'l to an operating arm, J, which is connected at the lower end to a eelitrally-pivoted lever, J operated upon by a cam, J, on a shaft, K,

ordinary manner.

suitably driven. The action of the cam raises the knife, and when it has passed its contact or high point the lever J 2 permits the knife to drop, which is accelerated and strengthened or enforced bya spring, J The knifeJ thus presses upon the weft-thread, which rests upon a block or support, fixed in the frame of the machine and severs the thread, so that the holder may be dropped or moved sidewise without affecting the thread which has been run into place between the warp-threads. The action of the knife is accurately timed to take place immediately upon the weft-thread (1* being drawn the entire width of the warpthreads.

The weft-threads are drawn through guides D held upon the carriage E, from suitable bobbins or spools. (Not shown.)

The construction of Jacquard harness by which I achieve the movement of the holders l) corresponds in the main particulars with the ordinary Jacquard harness well known in looms. Several features of novelty, however, have been added, which will appear in the following description:

The needles 1 1 are suitably suspended, guided, and operated, and the cords 2 2 pass through eyes or loops in the needles in the q The cords are fastened loosely in a perforated board at top by being knotted over said board. They are also provided with knots 3 at the point where they pass through a vertically-reciprocated board, 4. This vertically-reciprocated board 4 is provided with openings 5, which permit the knots 3 to pass, and with slots 6, opening into said holes or openings 5, which will not permit the knots 3 to pass. The slots 6 lie on the side of the holes next to the pattern-cards. With all of cords 2 hanging in said slots, so that the forward movement of the pattern-carriage will move all of the needles forward, (except the one that goes through the hole in the pattern-card,) the said forward movement of said carriage will move the needles forward and take all of the cords out of slots 6 except the one in the needle which goes through the hole in the pattern-card. This permits all the knots 3 topass through the openings 5 in board 4 except the knot on the string, which goes through the needle which has passed through the hole in the pattern-card. This cord remaining in the slot, the knot will remain on the upper surface of the slotted middle board, 4, and when said board is raised this cord will be raised or pulled up, which will raise the connection f and elevate the holder D, as before described.

The vertical reciprocation of board 4 is accomplished by arms 4, extending from the rock-shaft 4", (suitably operated, as hereinafter described,) and link 42, connected with board 4. The operation of the rock-shaft 4" is accomplished by means of a pitman, 4, connected to an end extension of one of the arms 4, as shown in Fig. 1, which pitman extends down to the operative parts of the loom shield is shown more fully in Fig. 9.

mechanism below and is thereby moved. The pitman 4 extends down and is attached to a lever, 4, as shown in Fig. 1, and the lever is worked by suitable crank or cam on shaft H, as shown in Fig. 2.

The pattern-card 7 is made of a continuous length of card-board or material of which loomcards are usually made, and is held upon roll 7 mounted on a frame or support, 8. The card 7 is provided with a line of perforations at bottom and top, which are taken hold of by projections 9 on the feed roller 10, by which the card is held and moved. After passing over this feed-roller, the pattern-card sheet is passed under small roller 11, over large roller 12, and onto winding-up roll 13, which latter is mounted on a pivoted arm, 14, which is caused to hold roll 13 against roller 12 with sufficient pressure to cause it to be rotated by a spring, 15. A shield, 16, is placed between roller 10 and the cardsheet, over which the sheet is caused to progress. This It is provided with a series of holes, 17, into which the needles, when they have passed through the pattern-holes in the card-sheet, are protruded. A reciprocatory movement toward and away from the needles is given to frame Sby means of the arms 8, which project through the frame of the Jacquard harness and are reciprocated by the arms 18, connected to rockshaft 19, which is operated by pitman 19 from the driviug-shaft below. The connection or pitman 19 extends down and is attached to a lever, 4", which is worked by a suitable cam or crank on shaft H, as shown in Fig. 2. I

The feed-roller 10 and roller 1 2 are operated by atrain of gearing, 20, to which is connected a ratchet-wheel, 21, in which a pawl, 22, which is attached to the fixed part of the frame of the Jacquard harness, works,and the backwardand-forward movement of the card-carriage causes the ratchet-wheel to be turned step by step, which, through the gearing above described, gives a progressive step-by-step move ment to the card.

For ordinary use the card is made about twelve holes deep. \Vhen more than twelve colors are required, instead of increasing the depth of said row of needles, and thus necessitating an increased width of the patterncard,

additional rows of needles are added and a sidewise motion given to the carriage holding the pattern-card. This sidewise movementis accomplished by using the bottom or lower three needles in each row of needles for operating the device which shifts the patterncard carriage sidewise.

As shown in 10, three rows of needles are used. As shown in this figure, the cords 2 from the second and third horizontal line of needles, counting from the bottom, are at tached to vertically-sliding bars 24 and 25, which have wedge-shaped cams or projections 24 on the upper ends thereof. These wedgeshaped cams or projections operate against the side of the arms S of the patterircard frame 8, thus forcing it sidewise and bringing the vertical row of holes in shield 16 opposite the proper row of needles. \Vhen it is required to bring the pattern-carriage back, the bars 2-1- are lbreed downwzitrd by means of a pivoted lever, 26, by means of the cords 2, which pass through the bottom line of needles.

The restm-atimr of the pattern carriage is accomplislml by springs 8", as shown in Figs. 7 and 8, which, being compressed by the action of the cams upon the bars 8, recoil. when the bars '24 and 25 are lowered and move the carriage over.

The cam on one of ,the bars tor instance, Q-t-is smaller than that on 25, so that the movement sidewise caused thereby will not be so great, and only throw the carriage suf- Jieiently to the side to shift from one vertical row of needles to the next, while the larger cam will shilft past one row and bring the shield it], with its line of holes, into line with a row of needles t-wo removes oti. dent that any number of rows of needles may thus be used. After each operation the carriage is ln'oughtback to the first row of ncedies by means of lever 26, to which the cords 2 of thelower line of needles pass, as already explained. I

The lever 26 centrallypivoted, as shown, and has a cross-pin, 26, in the end or limb thereof opposite to the end to which cords 2 are attached. As this end 01: the lever is caused to descend, the cross-pin 2U forces bars 24 and S5 downward until their cams 2i and 25 stand below the arm 8*,when the arms will assume the lateral position shown in Fig. 10.

A larger number of. cords are shown in some of the ligures ot the drawings than there are varnholders; but it is to be understood that in prz-ietiee there will be as many levers and cordsf' and yarn-holders as there are cords, while for convenience of illustration I have shown only a few of the said levers and yarn-holders.
